Description

FIELD OF THE INVENTION

The field of the invention relates to passenger seats, and, more particularly, to tray tables for passenger seats.

BACKGROUND

Passenger vehicles, such as aircraft, buses, trains, ships, and automobiles, include passenger seats in which passengers can be seated and otherwise use during travel. Traditionally, the living space for each passenger seat has offered passengers a limited ability to control and utilize their living space during travel, and the limited control and ability to utilize the living space may negatively affect the passenger's travel experience. For example, while some tray tables may include a personal electronic device (PED) holder, traditionally such PED holders are unable to stably support a PED and/or unable to accommodate different types of PEDs, and a passenger often must lean the PED against a seat back. In such cases, the PED may be damaged when the device is leaning against the seat back and when the seat back is moved to a taxiing, takeoff, and landing position as the device may lose contact with the seat back and potentially fall through the gap between the tray table and the seat back.

A tray table assembly 106 may be supported on the passenger seat 100 and includes a tray table 108 and one or more supports 110. In certain embodiments, the tray table 108 is movable between a stowed position and a deployed position relative to the seat back 104 via the support(s) 110 such that a passenger in an aft passenger seat (not illustrated) can selectively use the tray table assembly 106 as desired. FIG. 1 illustrates the tray table 108 in the deployed position. Optionally, and as illustrated in FIG. 1, when the tray table 108 is in the deployed position, a gap 112 may be defined between the tray table 108 and the seat back 104. Optionally, the tray table 108 may be slidable relative to the support(s) 110 to further position the tray table 108 relative to the seat back 104. As one non-limiting example, the tray table 108 may be slidable in an aft direction relative to the seat back 104 and when the tray table 108 is in the deployed position to position the tray table 108 closer to a passenger in the aft passenger seat. While the tray table 108 is illustrated as a single leaf tray table, in other embodiments the tray table 108 may have a plurality of leaves as desired. In one non-limiting example, in another embodiment the tray table 108 may be a bi-fold tray table with two leaves.

The tray table 108 may be formed of materials including but not limited to aluminum, stainless steel, aramid fibers, polycarbonate, polypropylene, other metallic materials, composite materials, and/or other similar materials as desired. As illustrated in FIGS. 1 and 2, the tray table 108 generally includes a forward end 114 and an aft end 116 opposite from the forward end 114. The tray table 108 also includes a top surface 118 and a bottom surface 120 opposite form the top surface 118. In certain embodiments, when the tray table 108 is in the deployed position, the top surface 118 generally faces upwards and the aft end 116 optionally is an aft-most portion of the tray table assembly 106. In some embodiments, when the tray table 108 is in the stowed position, the top surface 118 may face (and/or contact) the seat back 104, and the bottom surface 120 may face outwards and in the aft direction relative to the seat back 104.

In certain embodiments, the tray table 108 includes pocket 122 in the top surface 118 having a pocket surface 124 that is recessed into the tray table 108 relative to the top surface 118. In some embodiments, the pocket 122 may be closer to the forward end 114 than to the aft end 116, although the particular location of the pocket 122 in the top surface 118 should not be considered limiting.

In certain embodiments, the first end 144 of the first holder 140 is the first end of the overall holder assembly 132 and the second end 154 of the second holder 142 is the second end of the overall holder assembly 132. In the embodiment illustrated, the first holder 140 may be substantially the same as the second holder 142; however, in other embodiments, at least one characteristic of the second holder 142 may be different from the first holder 140. As some non-limiting examples, in other embodiments, a length and/or a width of the first holder 140 may be different from a length or a width of the second holder 142.

In various embodiments, as best illustrated in FIGS. 3A-C, the first end 144 of the first holder 140 is pivotably attached to the tray table 108 within the pocket 122 via a pivoting mechanism or device 160. The pivoting mechanism 160 may be various suitable mechanisms or devices as desired, including but not limited to pins, hinges, etc. The first end 144 of the first holder 140 pivotably attached to the tray table 108 enables movement of the holder assembly 132 between a stowed position (FIG. 3A) and a deployed position (FIGS. 3B-C) relative to the pocket 122. In some optional examples, at least a portion of the holder assembly 132 is within the pocket 122 in both the stowed and deployed positions of the holder assembly 132.

In various embodiments, the first end 152 of the second holder 142 is pivotably attached to the second end 146 of the first holder 140 via a pivoting mechanism or device 162. In certain embodiments, the second holder 142 pivotably attached to the first holder 140 enables movement of the second holder 142 between a folded position (FIGS. 3A-B) and an unfolded position (FIG. 3C) relative to the first holder 140. In some embodiments, and as illustrated in FIG. 3A, the second holder 142 is in the folded position when the first holder 140 is in the stowed position. The second holder 142 optionally may be movable between the folded position and the unfolded position while the first holder 140 is in the deployed position. In some embodiments, the holder assembly 132 is movable between the stowed position and the deployed position independently from movement between the folded position and the deployed position. However, in other embodiments, the holders 140, 142 may be coupled such that movement of the first holder 140 from the stowed position to the deployed position automatically moves the second holder 142 from the folded position to the unfolded position and vice versa.

Referring to FIG. 3A, in certain embodiments, in the folded and stowed positions, the second surface 150 of the first holder 140 may face the third surface 156 of the second holder 142. Optionally, in the folded and stowed positions of the holder assembly 132, the first surface 148 of the first holder 140 may be substantially flush with the top surface 118 of the tray table 108. In various embodiments, the holder assembly 132 in the folded and stowed positions is a minimum height of the holder assembly 132 relative to the top surface 118.

Referring to FIG. 3B, in the folded and deployed positions, the first surface 148 of the first holder 140 may face a first (e.g., forward) direction, and the fourth surface 158 may face a second (e.g., aft) direction opposite from the first direction. In various embodiments, the holder assembly 132 in the folded and deployed positions is an intermediate height of the holder assembly 132 relative to the top surface 118.

Referring to FIG. 3C, in the unfolded and deployed positions, the first surface 148 and the fourth surface 158 may face the first direction, and the second surface 150 and the third surface 156 may face the second direction. In various embodiments, the holder assembly 132 in the unfolded and deployed positions is a maximum height of the holder assembly 132 relative to the top surface 118. In certain embodiments, a user may utilize the holder assembly 132 to support the PED 130 when the holder assembly 132 is in the folded and deployed positions (FIG. 3B) or in the unfolded and deployed positions (FIG. 3C) as desired.

Optionally, and as illustrated in FIGS. 3A-C, one or more positioning feature(s) 164 may be provided to limit movement of the second holder 142 relative to the first holder 140. In the embodiment illustrated, the positioning feature 164 extends from the second holder 142 and selectively overlaps the first surface 156 of the first holder 140 in the unfolded position to limit movement of the second holder 142 relative to the first holder 140. In other embodiments, the positioning feature 164 may be provided on the first holder 140 and/or may be various other devices or mechanisms as desired for selectively limiting movement of the second holder 142 relative to the first holder 140.
